Climate change is one of the most pressing global environmental challenges of our time, and we are committed to contributing to a global solution by proactively managing our carbon footprint. We support the global response to climate change in two primary ways: by reducing our own carbon footprint and by delivering those commodities needed to mitigate carbon emissions.
Our Group minimum standard: Air emissions and greenhouse gas emissions and Position statement: Energy and decarbonisation are aligned with the ICMM’s climate change commitments, to SDGs 7 and 13, and to the UNFCCC (United Nations Framework Convention on Climate Change) Paris Agreement. Sibanye-Stillwater was one of 28 international mining and metals companies that committed to the new ICMM climate change position, announced ahead of COP26 (November 2021), which includes a commitment to net zero by 2050 for scope 1,2 and 3 emissions.
Our energy and decarbonisation strategy was refined in 2021 to support delivery on our long-term goal of achieving carbon neutrality by 2040 for scope 1 and 2 emissions. The near-term objectives of the strategy are to: 1) ensure energy security; 2) decrease energy and carbon costs; 3) reduce absolute GHG emissions; 4) improve the carbon footprint of our products and 5) enable value chain decarbonisation.
Delivering on our commitment to carbon neutrality by 2040
Implementation levers
Decarbonisation advocacy and just transition
Creating an enabling external
and internal environment for
decarbonisation
Demand-side energy
management (DSEM)
- Eliminating energy waste and enhancing operational efficiency
- Minimising load curtailment impact
Strategic energy sourcing
Sourcing low-cost
reliable renewable energy
Technology adoption
Leveraging technology, including digital, storage and hydrogen
Scope 3 emission reduction
Addressing our upstream and downstream emissions as part of our broader value chain
Carbon offsets
Responsible use of carbon offsets to neutralise our remnant hard-to-abate emissions
Mitigation of the risk of energy supply security at our SA operations remains critical. Our foremost decarbonisation lever is the ~765MW portfolio of renewable energy projects in South Africa, where electricity consumption contributes 92% of Group operational emissions. 164 MW of our solar and wind projects are complete, with the remainder to be completed by 2028. The implementation of energy efficiency projects has been instrumental in the continuous reduction of our carbon footprint. These include initiatives relating to ventilation optimisation at our SA gold operations, compressed air optimisation projects at our SA PGM operations, and the installation of solar arrays.
